About to try our XtraDB cluster on Kubernetes. Plan to deploy using the helm charts. I might have missed it, but I don’t see anything about persistent volumes? Anything I should be aware of here?

Hello @Henrik_Pedersen ,

by default we use persistent volume claims.  
If you look in the Custom Resource manifest ([cr.yaml](https://github.com/percona/percona-xtradb-cluster-operator/blob/main/deploy/cr.yaml)) note volumeSpec section:

```auto
    volumeSpec:
# emptyDir: {}
# hostPath:
# path: /data
# type: Directory
      persistentVolumeClaim:
# storageClassName: standard
# accessModes: ["ReadWriteOnce"]
        resources:
          requests:
            storage: 6G

```

For helm chart check out `pxc.persistence` in the [chart itself](https://github.com/percona/percona-helm-charts/tree/main/charts/pxc-db).
